BMW USA News - The New BMW 7 Series: Automotive luxury and innovations for the digital era.
BMW is leading the luxury segment into a new era that will be shaped by innovations in the fields of sustainability and digitalization.
The car’s impressive long-distance credentials are also down to the high-voltage battery’s excellent energy density. The extremely slim high-voltage battery with a cell height of just 4.3-inches is located low down in the vehicle floor and provides 101.7 kWh of usable energy. The heat pump technology used in the integrated heating and cooling system for the cabin and drive system also helps boost efficiency, as does the adaptive or individually adjustable recuperation feature. The high-voltage battery is heated using a dedicated 5.5 kW electric flow heater.
The Combined Charging Unit in the BMW i7 xDrive60 allows AC charging at a rate of up to 11 kW, while DC power can be taken on board at a rate of up to 195 kW. This means the range can be extended by as much as 80 miles in just ten minutes during a mid-journey stop at a high-power charging station.
Innovation: BMW Maps navigation system with improved functions for charging-optimized route planning.
The cloud-based BMW Maps navigation system boasts even better performance, enhanced accuracy and more intuitive destination entry in the new BMW 7 Series. Forming part of the standard BMW Live Cockpit Plus, the new-generation BMW Maps system enables very fast and dynamic route calculation based on precise real-time traffic data transmitted at short intervals combined with forecasting models.
As soon as the destination has been entered in the BMW i7, a charging-optimized route will be calculated if the vehicle’s current range is not enough to reach the destination. Further improvements have been made to both the calculation algorithm and the speed of calculation for charging-optimized routes. Important additional information about the charging stops has been added in the route summary, such as the estimated charge level upon arrival, the recommended charging time, and the target charge level for the onward journey. Live data is processed during the journey, allowing new charging stations to be automatically added to the itinerary if any of the stations originally planned for charging stops no longer have any availability. The driver is also now offered alternative charging-optimized routes, where available. By default, the system is set to ensure that the vehicle reaches both the final destination and the charging stops with a charge level of at least 10 percent. Drivers are now able to adjust this spare charge setting if required.
Innovation: more rounded charging curve thanks to new charging process.
The charging software from the BMW i4 and BMW iX models has been further refined for the new BMW i7. Once the high-voltage battery reaches a higher charge level, the new charging process aims to ensure the charging rate drops smoothly instead of following the previous “stepped” curve. This produces a more rounded charging curve overall, resulting in shorter charging times. Following an initial, temperature-dependent phase of constant power supply, the new process now also controls charging based on a continuous nominal voltage curve that makes allowance for the variables of temperature, recharged capacity, and charge level at start of charging.
Innovation: automated charging profile settings.
For the first time, the BMW i7 makes it possible to store customized charging settings for multiple individual charging points. These settings will then be automatically restored the next time the car returns to a memorized charging point. In addition to this, preheating of the high-voltage battery can also now be started manually in the BMW i7 when approaching a high-power charging station without the navigation system’s route guidance function activated.
Besides the improved charging software on board the new BMW i7, the cloud-based BMW Maps navigation system also helps to further enhance its performance on long journeys. For instance, a charging-optimized route is calculated as soon as the destination has been entered if the vehicle’s current range is not enough to reach the destination. Further improvements have been made to both the calculation algorithm used here and the speed of calculation for charging-optimized routes.
